CARPET SWEEPER.

Application filed May 6,

This invention relates to improvements in carpet sweepers. It relates more par ticularly to improvements in the, shell or case for a carpet sweeper; I

The object or the invention is to provide a light strong casing making use of flexible board such as composition board or plywood for the shell of the casing.

Objects pertaining to details and economies of construction of my invention will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiinertor my invention is clearly illustrated in tie accompanying drawing forming a art of this application, in which:

Fig. I is a perspective view or" my improved carpet sweeper case, the sweeper parts being absent.

Fig. 11 is an enlargec detail transverse see local elevation through the case.

Fig. III is an enlarged detail section showing the connection of the. ply-wood or composition board to the side rail,

Fig. IV is a detail view of the joints between the side andend parts taken on section line i i of Fig.

F V is an enlarged detail cross sectional view taken on line 55 of Fig. IV, the end being omitted.

In the drawing similar reference numerals indicate similar part-s in all of the views.

The parts or" the drawing will be referred to by their reference numbers. The shell 1 is made of fiber board, composition board, or thin flexible ply-wood havingquartercylindrical curved sides 2 and 3 at front and rear, respectively. The ends 4 are of wood other suitable material perforated and notched to accommodate the working parts of the carpet weeper.

Side rails 5 are provided connecting the square ends of the ends 4 together. These contain longitudinal grooves 6 to receive and 1924. Serial No. 711,360.

stiii'en the edges of the shell 1. pieces are gained or notched at? side pieces 5 Fig. 11.

Reinforce fillet blocks 8 are along the top edge inside of each end to reinforce and strengthen the connection between the shell and the ends. The ends are cut at an oblique angle at 9 and a supporting block 10 supports each corner of the shell which is extended at 11 beyond the end 4. This affords a broad support and attachment for the shell and strengthens the extension thereof, which, with the extended ends of the side bars, afi ords support for the guard bar of the carpet sweeper.

From this description it will be seen that my improved construction of case lends itself to a very cheap design of carpetsweeper case when fiber board, sheet metal or heavy pasteboard be made use of for the shell, because the edges are confined and supported and a broad attaching surface is provided. Such a structure is durable and avoids the metallic rattle of a metallic case.

Because of the curved conformation the shell itself. owing to its intimate connection to the other part.v adds to the rigidity of the structure which is a matter of considerable importance in the maintenance of the working parts in their most effective relation. The ease of operation of the carpet sweeper is greatly enhanced by such perfect support- Havingthus described my invention what The end into the as indlcated by dotted lines in I claim as new and desire to secure by Letters Patent is:

1. In a case for carpet sweepers, case ends curved on their upper edges, in combination with a suitable shell formed of flexible board with its front and rear curved in the arc of a circle and extended at each corner beyond said ends, side bars coterminous with said shell grooved on their tops to receive and retain the vertical edges of said shell, the said case ends gained into the said side bars, and supporting blocks at each corner of the case interposed between the shell and ends conformed and secured to the inner surfaces of said shell and secured to said ends, for the purpose specified.

2. In a case for car vet sweepers, case ends curved on. their upper edges, in combination with a suitable shell formed of flexible board with its front and rear curved in the are of a circle, and side bars coterininons with said shell groo' 'ved on; their tops to receive and retain the vertical edges of said shell, the said case ends gained into the said side bars to the inner face of said groove whereby the side bars securely retain the said shell against the said ends, for the purpose specified.

In Witness whereof I have hereunto set my hand.
